Problems solved by technology

However, after the compressive strength of concrete is increased, its tensile strength, shear strength and coarse aggregate strength are relatively low, and the ductility is reduced, thus reducing the seismic performance of high-strength concrete structures.

Embodiment

[0025] A new type of steel-concrete composite shear wall with a stiffening plate between the steel plates on both sides, that is, a multi-cavity steel plate-high-strength concrete composite shear wall, including an outer double-layer steel plate with a stiffening steel plate and a concrete shear wall. Pour high-strength concrete (above C60) in the outer double-layer steel plate with stiffened steel plate, and the concrete and the steel plate are connected by bolts. The outsourcing double-layer steel plate is surrounded by four thin steel plates on four sides to form an outsourcing formwork that completely wraps the concrete. The stiffening steel plates are arranged between the steel plates on both sides of the shear wall, penetrate from top to bottom in the steel plates on both sides, the stiffening steel plates are welded on the steel plates on both sides, and the stiffening steel plates are perpendicular to the steel plates on both sides. The stiffening steel plates separate...

Abstract

The invention provides a steel plate and high-strength concrete combined shear wall which comprises outer covered double-layer steel plates and high-strength concrete poured between the outer covered double-layer steel plates, wherein multiple rows of bolts are arranged on surfaces on the opposite sides of the outer covered double-layer steel plates. According to the invention, the concrete is filled between the double-layer steel plates, the steel plates and the concrete are tightly coupled by using the bolts and the concrete and the steel plates are mutually restrained, so that the deformability of the inner-filled concrete is increased, the ductility and the energy-dissipating capacity of the shear wall under the load effect are greatly increased, the structure of a double-steel-plate combined shear wall is simple, the outer steel plate can be used as a template and the construction is simple and convenient.

Description

technical field [0001] The invention belongs to the technical field of steel and concrete composite structures and mixed structures, and in particular relates to a double-layer steel plate concrete shear wall structure. Background technique [0002] Shear wall structure is a kind of anti-lateral force system against horizontal load. Under the earthquake, the shear wall not only bears most of the seismic shear force, but also plays an important role in dissipating seismic energy. The quality of its seismic performance plays a decisive role in the seismic performance of the entire structure. Therefore, the research on the seismic performance of shear walls is of great significance for improving the overall seismic performance of high-rise and super high-rise structures. [0003] The use of high-strength materials in engineering structures can not only meet the needs of modern engineering structures for high-rise and large-span development, reduce the cross-sectional size of s...
